The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
The self-driven refrigeration system of carbon dioxide as shown in Figure 1, by dioxide bottle 10, needle-valve 20, first cooling heat exchanger 30, second cooling heat exchanger 40, first capillary 50, gas-liquid separator 60, evaporimeter 70, blower fan 80, second capillary 90, heat exchanger 100, valve is connected in sequence by pipeline, the output of dioxide bottle 10 links to each other with the first input end of first cooling heat exchanger 30, first output of first cooling heat exchanger 30 links to each other with the first input end of second cooling heat exchanger 40, first output of second cooling heat exchanger 40 links to each other with the input of first capillary 50, valve comprises check valve 140 and stop valve 150, the output of heat exchanger 100 links to each other with the input of check valve 140, and the output of check valve 140 links to each other with the input of stop valve 150.
As preferred version of the present utility model, first cooling heat exchanger 30 also is provided with second input and second output, second cooling heat exchanger 40 also is provided with second input and second output, the gas output end of gas-liquid separator 60 links to each other with second input of second cooling heat exchanger 40, second output of second cooling heat exchanger 40 links to each other with the input of blower fan 80, the output of evaporimeter 70 links to each other with second input of first cooling heat exchanger 30, and second output of first cooling heat exchanger 30 links to each other with the input of blower fan 80.Like this, can the gas of discharging from gas-liquid separator 60 and evaporimeter 70 be cooled off once more, merge together, it is after 80s to drive blower fan, enters to continue evaporation in the heat exchanger 100 or utilize temperature difference heat absorption again, and refrigeration is better.
The concrete course of work is as follows:
Fluid flows out from dioxide bottle 10, adjust flow through needle-valve 20, first cooling heat exchanger 30 and second cooling heat exchanger, 40 priorities of flowing through are successively carried out twice cooling, reduced the enthalpy of carbon dioxide gas-liquid mixture, then flow directly into first capillary 50 and carry out throttling, as preferred version of the present utility model, be preferably 35bar through the pressure after 50 throttlings of first capillary; Fluid after the throttling enters gas-liquid separator 60, the liquid inflow evaporator of separating 70 evaporates heat absorption, reduce environment temperature, as preferred version of the present utility model, between the liquid output of separator 60 and evaporimeter 70, be provided with liquid-sighting glass 110, Pressure gauge 120 and thermometer 130 at gas, it is in order to observe the phasic property of refrigerant fluid, not had liquid if observe in the refrigerant flow path, showing that the refrigerating capacity of system is approaching exhausted that liquid-sighting glass 110 is set; Setting pressure table 120 and thermometer 130 are in order to determine the pressure and the temperature of internal flow, better control system; Refrigerant gas behind the outflow evaporimeter 70, second input of first cooling heat exchanger 30 of flowing through cools off, and second output by first cooling heat exchanger 30 flows out again; Second input that the gas that the gas output end of while gas-liquid separator 60 is separated enters second cooling heat exchanger 40 cools off, second output by second cooling heat exchanger 40 flows out again, converge mutually with the gas that flows out and cool off by evaporimeter 70 through first cooling heat exchanger 30, and can be used as the driving force of blower fan 80, blower fan 80 is sent into chilled air in the required environment and is gone.As preferred version of the present utility model, blower fan 80 is pneumatic blower fan, and in actual use, blower fan 80 also can change battery into and drive, and perhaps the two combination drive all is feasible; Gas after converging is through the second capillary 90 throttling step-down once more, as preferred version of the present utility model, pressure after the throttling this time is preferably 5.5bar, gas after the throttling heat exchanger 100 of flowing through again, in heat exchanger 100, part does not have the liquid of vapour warp to continue the evaporation heat absorption, cryogenic gas also carries out the heat exchange heat absorption by sensible heat and air at room temperature, the low-voltage high-temperature carbon dioxide gas basis of outflow heat exchanger 100, the check valve 140 of flowing through is again through stop valve 150, safe discharge system, because exhaust outlet also has certain pressure and carbon dioxide self characteristics, thus need enter in the atmospheric environment with certain flowability, and exhaust outlet upwards is provided with.
